Volvo - V70 :: Strange Hollow Noise Like A Whistle Blowing - Fuel Pump?
I have a 2000 V70/XC volvo with 95K miles. I began hearing a strange hollow noise, like a whistle blowing. I took it to the dealership where I bought the car and they said it was the fuel pump. I asked them if it was bad and needed to be replaced and the said they weren't sure about having it replaced right away. They said sometimes it will make that noise and the fuel pump could last for months and sometimes for years. They even suggested to just drive it until it fails then replace it. some say it could never go out. But it bothers me because it is the car that my wife drives daily taking kids around and running errands and so forth. I am always worried that she could get stuck somewhere anytime. So I am not sure what to do.

I just bought my first .:R32. Having a few minor issues:
1. When I open the door in the morning, the fuel pump primes the system and makes a high pitched sound (kind of like RFI). It's there when I have the car on also. So do you think I should buy a new pump and take it with me just in case?
2. This was happening before I bought the car. When I first move either forwards or backwards there is a clicking sound coming from the right front of the car. After I get moving, it goes away.
3. Just replaced the front right coilover assembly and there is a clunking noise coming from the strut (I think). What it could be? Maybe strut top bushing? Or ball joint making weird noises?

This has happened twice so far, both with around 1/2 tank. After driving for ~25 minutes to work, I will go to shut the car off, and after pushing the key in and pulling it out, there is a mechanical noise from the rear of the car that lasts for about 2 full seconds. Is this the sound of the fuel pump on its way out? Or just an electrical gremlin (no! not in a VW!)?

I worked with my buddy troubleshoot and remove a faulty fuel pump. He received it a week or so later and did the install himself. After this, he states that while pumping gas at the gas station the nozzle no longer cuts off automatically when full causing overflow. He says this has happened at different stations and different pumps. I told him to go double check connections and that everything was sealed. I am wondering what could be causing it..

Passat (B5) :: 2002 / 1.8t - Whistle Noise On Start
I was noticing today when i started my car that it was making a whistle noise. So naturally i popped the hood to find the source of the noise. It is from this hose that connects to my header it has this crack in it and it is sucking air in.

View 2 RepliesPassat (B6) :: Loud Whistle Noise When Accelerating
For a week now, my car whistle pretty loudly (I can hear it windows closed) when accelerating. After reading about 2.0t problems, I thought it was either a bad DV or PCV. I tried to diagnose if my problem was related to a bad pcv. So I disconnect the tube going from the intake to the pcv and plug the hole on the intake. Then I went for a ride and it whistle like before...so does this test confirm that my pcv isn't my problem?
As of now, I never saw traces of oil around the oil filler cap. When the engine is running, as soon as I press on the accelerator(even lightly), the whistle begin. As soon as I remove my foot, it whistle for a second then it stop. At a stop, if I press on the accelerator, the whistle will begin at only 5500 rpm and up.
No CEL so far related to lost of boost(I had a cel last week and they change fuel sensors and regulator). Also, the car pull pretty constantly but seem less powerful than before.
Lexus GX 2004-09 :: 2005 - Bizarre Whistle Noise From Front Right Wheel?
I have a 2005 Lexus is 200, but I'm not sure if the model even matters for my question.
Anyway, I'm hearing a strange whistle from the front right wheel, and I'm sure the sound comes from it. I made a youtube video so you can get the idea.
The sound starts at around 50km/h speed and it does not change after that, meaning that it doesn't become harder if I speed up and if I slow down to 40 or 20 it does not go away. But if the car is cold, it does not start until I reach 50-60km/h speed.
Also, I tried turning the engine off on neutral while driving and it did not influence the noise in anyway. So its not related to motor.
In the video it starts from 11s and you can hear it clearly starting at 57s when I speed up. Because of other sounds you probably can not hear it as clear as I can, but just listen to the whole video and I think you will get a clear idea.
Here is the video: [URL] ....
The thing is, I went to a decent repair garage and they could not say what it is. So assume that basic things like breaks or the like were checked by mechanics.
I want to add that there probably was a hard hit to the right wheel recently while driving in reverse, I say "probably" because the person did it does not want to admit it and I can only guess, so I dont have an idea how it went. But I found a deep slicing (not sure if its the right word) on the right wheel tire and it was so deep (and around 5cm in width) that I had to replace the tire. So assume that there could have been a hard hit and the wheel took damage. The noise started a couple of the days after I found it.
Ford Fuel System :: E350 - Fuel Tank / Pump Noise After Cutoff
This van has had a couple of fuel pumps, no surprise there, and i need to look through my paperwork and find out how many miles the current one has on it, but it has the STRANGEST habit I've ever had on any vehicle. Starts fine, runs fine, no fuel pump noise when van is running, and when you turn it off, the fuel pump creeks on and off for several minutes.
I mean a strange creaking noise almost like a shorted electrical device or a vehicle's brakes when you park it on a hill and the breaks creak as it settles into place. I'm probably doing a lousy job of describing this but i don't know how else to describe it!
ALSO, if you lay under the van and wait til it stops creaking, you can tap the bottom of the tank and it will creak for a few more seconds. You can tap repeatedly and make it creak more. Is it about to explode? Can i trust it on a road trip?

I have a k04 turbo on the passat. (2000 b5) been having problems with it for longest time. however one night i was cruisn around and suddenly when car boosted the turbo went from the typical whistle to a whistle with a distinct buzzing noise (no to loud but very noticeable) almost like a bery dull sounding supercharger.
Ripped inlet hose off found that where the clamp is to hold on to turbo inlet was slit all the way through got new inlet hose hooked it up nothing happened. checked all turbo charge pipes and lines am going to double check again tomorrow. does this sound like a turbo issue or a leak issue. There is no loss in boost car was fixed and now runs great ... but this buzzing sound is annoying and kinda worrying me at the same time.

View 4 RepliesPassat (B6) :: CEL Code - Fuel Pump Defect
Had check engine light come on as the car stalled. Brought the 09 passat to vw dealer and was told the engine code showed fuel pump defect. For 1,000.00$ they changed the fuel pump and did a fuel system cleaning. Also had an oil change done.
Drove away less then 10miles, and the same thing happened. Bringing it back tomorrow, but how to handle the situation? Already contacted AMEX regarding the situation to potentially open a dispute charge claim.
If the MIL indicator is on, does it give a direct code to the problem? I suggested it could be the manifold issue, but they said that's not it.
Passat (B5) :: Car Quit On The Road, Bad Fuel Pump Diagnosed
The car quit on the road and I diagnosed a bad fuel pump. Multiple tests confirmed the pump had failed. While we were doing the diagnosis, I noticed some strange behavior when monitoring voltage to the pump. While supply voltage was present during cranking, none was applied to the pump when the key was first turned to accessory. I decided to chase one thing at a time and replaced the pump (and fuel filter, since it had been too long since last replacement and I wanted to "cover all bases").
After pump replacement, I opened the coupling in the supply line before the fuel rail to confirm proper operation. When the key was initially turned to accessory (multiple times to prime everything), there was NO fuel flow. When we then cranked it, fuel was present very quickly. After reconnecting the line, a couple of rounds of cranking got the fuel pressure up and the car started and ran perfectly. A quick VAG-COM check showed no codes. I test drove it and then shut it down. Immediately after shut down, I switched the key to accessory and the fuel pump started right up. After doing this 4-5 times with a few minutes pause in between, I pronounced the car "good" and finished up.
This morning, I jumped in, turned the key to accessory and heard......nothing. No fuel pump running for the normal 2-3 seconds. I cranked it and it took two rounds of 4-5 sec cranks for it to fire and run (normally). I assumed it needed time to build fuel pressure. I then drove it for 20 minutes, parked it for 45 minutes and when I restarted it, it took a longer than normal crank period (maybe 3 seconds) to fire and I did NOT hear the pump run in accessory position. The rest of the day was with short stops and I could always hear the pump start in accessory and the car always fired up instantly. I have the Bentley CD and analyzed the wiring harness. It looks like the fuel pump relay is only commanded to operate by the ECU - there is no external input to the relay coil I can see (ground or B+).
The bottom line is that SOMETIMES the pump is commanded to run in ignition switch accessory position and sometimes it isn't. The "isn't" always seems to be after the car has sat for a while. Is there any combination of failed sensors that would cause the ECU to NOT command the pump to run for it's few seconds in accessory position ? Obviously, the next step is the FP relay but I hate to just throw parts at the car without some sort of troubleshooting and the repeatability of the problem with sitting time leads me to believe it may be more of a relay DRIVE problem then the relay itself.
Passat (B5) :: Fuel Pump Has No Sound While Cranking, Car Won't Start
98 Passat 1.8T FWD
Car will not start. No sound from fuel pump while cranking. Pulled up the carpets and pulled the cover and connector from the fuel pump. Ive heard the relay is the common problem. I tried checking the voltages on the harness and we get 0 while cranking. Pulled the relay and we get a resistance from T pin to pin 86. I did notice a yellow color on the white connector on the fuel pump itself around the middle two contacts.
Passat (B7) :: Connector On HP Fuel Pump Regulator Broke Off
Hit a bump in the road, car hiccuped then EPC and MIL illuminated. Scanned it with Carista and showed low fuel pressure. Looked under engine cover... Lo and behold! Connector is plugged in but male portion on regulator is snapped off!!! Needs whole fuel pump assembly at 25,000 miles!
